The silicone tube and silicone belong to organic silicon products, they are silicon - Oxygen ( Si- O) Key chain structure, C - Key the key for 82 C. 6 kcal/mol, Si - O can key in the key in the organic silicon is 121 kcal/mol, so the thermal stability of silicone products, high temperature ( Or radiation exposure) Molecular bonds do not broken, do not break down. Organic silica gel not only resistant to high temperature, and low temperature resistant, also can be used in a wide range of temperatures. Chemical properties and physical mechanical performance, under the influence of temperature is small. The main chain of - silicone products Si- O- And no double bonds exist, therefore not easy by uv and ozone decomposition. Organic silicon is better than other high polymer materials and the thermal stability of the irradiation resistance and weather resistance ability. The service life of organic silicon in the natural environment can be up to several decades. Polysiloxane compounds are known to one of the most inactive compounds. They are very resistant to biological aging, and the animal body without rejection, and has good anticoagulant capability. Main chain of organic silicon is very smooth, the intermolecular force is much weaker than hydrocarbons, therefore, than with low molecular weight hydrocarbons viscosity, surface tension, surface energy is small, film forming ability. This kind of low surface tension and low surface energy is the main reason why it for various applications: hydrophobic, foam, foam stability, adhesion, lubrication, polishing, and other excellent performance. Organic silicone products have good electrical insulating properties, the dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistivity and surface resistivity of all came out on top in the insulation material, and their electrical performance is affected by temperature and frequency is small. As a result, they are a kind of stable electric insulation material, is widely used in electronics, electrical industry. Organic silicone besides has excellent heat resistance, but also has excellent water repellency, which is using electrical equipment in wet conditions with high reliability.
